Application filed March 5, 1920. Serial No. 363,410.

To all whom it may concern:

Be it known that I, JAMns D. GARVEY, a citizen of the United States, anda resident of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Mop Wringers, of whichthe following is a description, reference being had to the accompanyingdrawings, which form a part of my speci- 1 fication.

My invention relates to wringers more especially intended for thewringing of floormops and the like; the invent-ion having for its objectthe provision of a construction whereby ample pressure maybe applied tothe strands of the mop, or other article from which the water is to bewrung, while at the same time enabling the operator to easily pass thestrands of the mop between the rollers of the wringer portion of thepail without necessitating a severe upward pull on the mop as is thecase with certain construction of mop wringers at present in use.

With my improved construction, the user is enabled to apply therequisite pressure on the strands of the mop through the manipulation offoot-actuated means and while the strands of the mop are firmly pressedbetween the rollers of the wringer, the operator may cause a positiveoperation of the rollers through the operation of a suitable hand-crankwhereby both rollers will be given positive actuation and themop-strands positively fed through the wringer to cause a thoroughwringing of the mop or other article. i i

My invention also contemplates means whereby the water wrung from themop or other article will be prevented from splashingout or passingalong the rollers to the pail exterior; said means also ensuring aproper positioning of the mop during wringing operation; the inventionalso contemplating means whereby the wringerrolls will be automaticallyforced into separated relation upon release of the foot-operatedmechanism; while at the same time a pail is provided which is not easilytilted and which will not mar the floor during its use.

The objects and advantages of my invention Will be readily comprehendedfrom the I following detailed description of the drawin s, whereinzigure 1 is a' perspective view of my improved mop wringer with portionsof the bail or handle broken away.

Figure 2 is a detail plan view of the rolleroperating mechanism asdisclosed on the near or crank side of the pail as shown in Figure 1.. yI I Figure 3 is a detail view in side elevation of the mechanism shownin Figure 2, with the crank and sprocket ends'of the roller journalsbroken away. 7

Figure '6 is a side elevation of'theiconstruction shown in Figures land5; the view being taken substantially at ri ht angles (to Figure 4andlooking toward t efoot-oper ated mechanism. 1

Figure 7 is a top plan viewof-the' construction shown in. Figures 4,[5and6.

In the particular eXemplificationflof-the invention, as disclosed inFigures Ho 3, it comprises a suitable sizedfluid-holding ves sel or pail10, provided. with a bail, a portion whereof is shown at 11 in. Figure1, of such construction and so secured as not to interfere with thewringer mechanism later to be described. The bottom of the pail ispreferably provided with four standards or supports disposed atequi-distan'ces apart about the lower part of the vesselfas shown at 12Each support 12 comprises a strip of substantially heavy sheet metal,prefer ably galvanized, having a portion arranged flush with'the sideof'the vessel 10 and rivetedthereto as shown at 13; while the reattached portion extends outwardly away from the bottom of the pail orvessel and terminates in a horizontally disposed foot 14 which is curvedslightly upward. I prefer to cover the'feet 14: with a suitable fabricor rubber as at 15, which is maintained in placexby lacing as shown,thus permitting the covering of rubber to, be readily" removed whenit-becomes worn; a The four supports or] standards 12 are braced by themetallic strips or braces 16 riveted at one end to the lower part of thesupport and extending upwardly toward the bottom of the vessel or pail10 to which the other end is suitably secured by rivets or otherwise. y

I A very firm and rigid support for the pail is thus provided; thesupports extending llO.

outwardly suflicient to prevent any possibility of tipping; while at thesame time the rubber covered feet will prevent marring of polished orpainted floors.

By supporting the pail on standards or supports, the bottom of the pailis maintained away from the floor and the possi bility of injuring apainted or polished floor, by reason of hot water in the vessel, will beobviated. At the same time, the supports hold the vessel at an elevationsurlicient to permit operation of the foot-pedal 17 which is disposedslightly beyond one side of the vessel as shown in Figure 1 and has itslever portion 18 extending centrally beneath the pail to the oppositeside where it is pivotally mounted in a bracket or loop secured tobottom of the vessel, as shown at 19 in Figure 1; one of the supports orstandards 12 being shown broken away to disclose'the pivot or fulcrumpoint of the lever 18.

At diametrically opposite points at the top of the vessel 10, I providebrackets 20, which are preferably riveted to the sides of the pail; thebrackets comprising flat strips of metal with the ends twisted so as tolie flush with the pail-sides, while the intermediate portion isdisposed a slight distance above the top of the pail and extends in ahorizontal plane. To this intermediate portion, I secure a rectangularloop portion 21, which is shown riveted in place; the loop portionproviding a bearing for the trunnions of the two rollers 22 and 23.

The bracket 20 at the opposite side of the pail or vessel is identicalin construction and also provided with a similar rectangularloop-portion 21 to provide suitable bearing for the adjacent trunnionsor ends of the two rollers 22 and 23. The roller 23 is rotatably mountedin the loop members 21, but held against movement longitudinally of theloop members in any suitable manner, as for example by the pin 24:, seeFigure 3. The pin may, if desired, be made removable so as to enable theremoval of the roller 23 for repairs or replacement. The roller 22 isintended to move lengthwise of the loop members 21 and therefore has theends of its trunnions which extend to the outside of the loop members21, provided with suitable clips or plates 25 loosely mounted thereon topermit rotation of the trunnions in the plates or clips 25. The top partof each loop member 21 is provided with an extension 26 disposedhorizontally, with the ends o1 the extensions shown curved outwardly.One end of a suitable spring 27 is secured to the outwardly curved endof each extension 26, while the other end of each spring 27 is securedto the adjacent end of the plate or clip 25. The springs 27 maintain theroller 22 at the spring ends of the members 21, as shown in Figures 1, 2and 3, namely in separated relation with the roller 23; the springsapparent from the construction shown and described that when thefoot-pedal 17 is depressed, a pull will be exerted on the cables orcords 28 whereby the roller 22 is forced against the action of springs27, toward the roller 23. Preferably one end or trunnion of each roller22 and 23 is provided with a sprocket-wheel 30 and 31, respectively,adapted to be brought into intermeshing relation when the roller 22 isbrought into close relation with roller 23 through the action of thepull exerted by cords 28 when toot-pedal 17 is depressed. The trunnionof roller 23 at a point beyond or tothe outside of sprocket 31 isprovided with a crank or handle 32 secured thereto to enable rotation ofthe roller 23 and by reason of the intermeshing relation of thesprockets 30 and 31 positive rotation will also be imparted to roller22; it being understood, of course,that the sprockets are so formed topermit contact between the main surfaces of the rollers. With thisconstruction, a positive feeding of the mop strands through the wringerwill be had, without the necessity of exerting an upward pull on themop; a positive wringing action being obtained without the exertion ofpower or force as is the case with certain types of mop wringers atpresent in use.

The brackets 20 with the loop members 21 are preferably provided withthe upwardly disposed and slightly outwardly flared shields or guards33, extending throughout the length of the loop members and on what maybe termed the inner sides thereof; that is on the sides adjacent themain portion of the rollers 22 and 23. These guards will not onlyprevent the mop strands catching between the intermeshing sprockets 30and 31, but will also prevent the water from flowing toward the ends ofthe rollers and beyond the sides of the pail.

In practice, the user inserts the mopstrands, or cloth, between theseparated rollers 22 and 23, then depresses foot-lever 17, sutlicientlyto draw roller 22 into juxtaposition with roller 23, thereby inducing anintermeshing relation between sprockets 30 and 31 and while maintainingthe rollers in such juxtaposed relation, by keeping his foot on thefoot-pedal 17, grasps crank or handle 32 and rotates the latter inclockwise direction, causing roller 23 to be likewise rotated, whileroller 22 will be positively rotated but in counter-clockwise direction,thereby inducing the mop-strands to be fed upwardly through the wringer.

In Figures 4 to 7 I show a modified form of my invention; with theVessel or pail 10 constructed substantially similar to that shown in theprevious figures and as heretofore described; the sides of the vessel orpail, adjacent the top, being provided with similar brackets 20, onwhich are secured rectangular loop members 34, substantially similar toloop members 21, except that in this construction one end of eachrectangular loop member 34 is shown slightly reduced where they receivethe trunnions of the roller 23, which latter is held against movementlongitudinally of the loop-members in any suitable manner as for exampleby the pin 35. The other roller 22, like in the previous construction,is intended to not only rotate 1n the loop-members 34 but to also slidelengthwise thereof. In this construction the footpedal 17 is secured tothe lever 18 which is preferably disposed centrally beneath the pail orvessel 10, with its end pivotally secured in a bracket, as at 19, whichmay be similar in construction to that employed in Figure 1; the bracketbeing suitably secured to the lower end of the pail or vessel. Theconstruction shown in Figures 4 to 7 comprises a rod 36 pivotallysecured at its lower end at the point 37 to the lever 18, while theupper end is pivotally secured at 38 to a link '39 which latter ispivoted at 40 to a bracket 41. The bracket 41 extends to opposite sidesof the pail 10,,as shown in Figure 7, with the outer ends of the bracket41 bent at an angle to the main portion and arranged to receive thetrunnions'of the roller 22; the ends of the brackets 41 being slidablyarranged in the loop-members 34. The side of the pail 10 is providedwith abracket or loop 42 through which rod 36 slides; and this loop 42also provides a seat for a coil spring 43 which is disposed about therod 36, with the upper end of the spring bearing against a laterallydisposed pin 44 secured in rod 36. With rod 36' slidingly held inposition against the side of the pail or vessel 10, it is apparent thatwhen foot-pedal 17 on lever 18 is depressed, the downward pull exertedby rod 36 on link 39 will force bracket 41 toward the opposite end ofthe loop members 34 and therefore cause the roller 22 to be brought intojuxtaposition with roller 23.

The trunnions of the rollers 22 and 23', like those in the previouslydescribed construction, are each provided with the sprockets 30 and 31,respectively, adapted to have intermeshing relation when the rollers arebrought together through the depression of foot-pedal 17 against theaction of spring 43 it being understood, of course, that link 39 is oflength commensurate with the distance that roller 22 is to move in theloop members.

With the spring 43 arranged as described, it I is clearly evident thatwhen pressure on footpedal 17 is withdrawn, rod 36 will be forcedupwardly through the action of spring 43, causing link 39 to be movedupwardly into the position shown in Figure 4, thereby pulling' bracket41 with roller 22 toward the ad jacent side of the pail. The trunnionofroller 23, like that shown in Figural, is provided with a hand-crank 32whereby rotation is given to roller 23 and to roller 22 through theaction of intermeshing sprockets 30 and 31.

Instead of employing the braces. 16, shown in Figure 1, the supports orstandards 12 of the pail or vessel may be provided with brace-rods 45extending from support to support at a point preferably adjacent thelower ends of the supports, as shown in the drawings, thus not onlyensuring a rigid bracing effect for the supports, but also providingsufiicient space for the movement of the footpedal and lever.

I have shown the roller provided with sprockets merely at one end ofeach roller,

but whendesired both ends of the rollers may I be provided withsprockets adapted to in termesh; and instead of employing a cable orcord 28, it is evident that a suitable chain may be employedto effectthe same operation described; and other modifications may be made incertain details of construction without departing from the spirit of myinvention.

What I claim is A device of the character described, comprising a pailprovided with bracket members secured to the sides thereof and disposedhorizontally above the top, the horizontally disposed portion of eachbracket being provided with a longitudinal slot, a pair of rol1- ers,the trunnions whereof are rotatably mounted in the slots of saidbrackets, means whereby one roller is held against horizontal movementwhile the other'roller is adapted to move lengthwise of said slots,means whereby said rollers are normally held in spaced relation,sprocket wheels secured to the trunnions of said rollers, to the outsideof the bracket member, said sprockets being adapted to intermesh whensaid rollers are brought into juxtaposition, a foot-pedal op erativelyconnected with the trunnions of the movably mounted roller, whereby thelatter may be moved against the action of said second means and broughtinto juxtaposition with the other roller and the sprocket wheels
